Product Description:

We are company that have many years experience and professional manager team and engineer team and sales team, sure we will provide you high quality of pipe and professioanl service.

Seamless pipe possesses a hollow section and without seam around the strip steel. It is made with solid bar or steel ingot by perforating machine. As the facture process does not include any welding, seamless pipes are considered to be stronger and more durable. Generally speaking, seamless pipe has better pressure resistance and security than other classifications, and was usually more easily available than welded pipe.

• High working accuracy

• High strength

• Small inertia resistance

• Strong therming dissipine ability

• Good appearance

• Reasonble price

Q:Are the welded and galvanized tubes the same weight?

The same specifications of welded pipe and galvanized pipe weight is not the same, the general welding tube weight, galvanized pipe light.

It is used to transport water, gas, air, oil and heating steam, and generally lower pressure fluid and other purposes of welded steel pipe. The wall thickness of the steel pipe is divided into ordinary steel pipe and thickened steel pipe. The end of the pipe is divided into non - threaded steel pipe (light pipe) and threaded steel pipe. The specification of steel pipe is expressed by nominal caliber (mm). The nominal diameter is the approximate value of the inner diameter. Usually used in inches, such as 11/2. The welded steel pipe for low pressure fluid transportation is used as the main pipe of galvanized steel pipe for low pressure fluid transportation except for directly conveying fluid

Q:What's the actual size of the DN25?

DN25 refers to the theoretical size of the inner hole of the pipe. That is to say, the theoretical dimension of the inner diameter of the pipe is 25 (the metric tube refers to the inner diameter, and the English tube is also to indicate the inner diameter, for example: 3/8, the inner diameter is 9.525, and the diameter of the 1/2 is 12.7, and the diameter of the 5/8 is 15.875). The outer diameter is theoretical in diameter, plus the wall thickness specified by the state (which is artificially specified and has no formula)The theoretical diameter of DN25 is 25, and the outer diameter is Phi 33.7 and phi 32(but there is also the outside diameter of the mark. The mark is: the outer diameter * wall thickness, such as: 32 * 2, that is to say, the outer diameter is 30, the inner diameter is 26)

First, you have to choose at least three or more types of materials. Modeling is a little complicated. Strongly recommended that the landlord to see "ANSYS in civil engineering applications", where there is such an example, you step by step, step by step back, and then in accordance with their own requirements modeling, OK. Wish you success

Q:Difference between seamless steel pipe and welded pipe

Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.

Q:304 stainless steel tube with the diameter of 25*2-3 is what mean

This is according to the "water drawing standards" (GBT50106-2001) in 2.4.2-2 seamless steel pipe, welded steel pipe (straight or spiral seam), brass, stainless steel pipe, pipe diameter should be D diameter * thickness representation (such as D108 * 4 and D159 * 4.5); and the provisions of the habit of acting D with seamless pipe diameter.

Q:Seamless steel pipe 8162 and 8163 what is the difference?

GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
